Cosmos SDK Documentation

NOTE: This documentation is a work-in-progress!

• Overview

  • Overview - An overview of the Cosmos-SDK
  • The Object-Capability Model - Security by least-privilege
  • Application Architecture - Layers in the application architecture

• Install - Install the library and example applications

• Core

  • Introduction - Intro to the tutorial
  • App1 - The Basics
    • Messages - Messages contain the content of a transaction
    • Stores - KVStore is a Merkle Key-Value store.
    • Handlers - Handlers are the workhorse of the app!
    • Tx - Transactions are the ultimate input to the application
    • BaseApp - BaseApp is the base layer of the application
  • App2 - Transactions
    • Amino - Amino is the primary serialization library used in the SDK
    • Ante Handler - The AnteHandler authenticates transactions
  • App3 - Modules: Auth and Bank
    • auth.Account - Accounts are the prototypical object kept in the store
    • auth.AccountMapper - AccountMapper gets and sets Account on a KVStore
    • auth.StdTx - StdTx is the default implementation of Tx
    • auth.StdSignBytes - StdTx must be signed with certain information
    • auth.AnteHandler - The AnteHandler verifies StdTx, manages accounts, and deducts fees
    • bank.CoinKeeper - CoinKeeper allows for coin transfers on an underlying AccountMapper
  • App4 - ABCI
    • ABCI - ABCI is the interface between Tendermint and the Cosmos-SDK
    • InitChain - Initialize the application store
    • BeginBlock - BeginBlock runs at the beginning of every block and updates the app about validator behaviour
    • EndBlock - EndBlock runs at the end of every block and lets the app change the validator set.
    • Query - Query the application store
    • CheckTx - CheckTx only runs the AnteHandler
  • App5 - Basecoin -
    • Directory Structure - Keep your application code organized
    • Tendermint Node - Run a full blockchain node with your app
    • Clients - Hook up your app to CLI and REST interfaces for clients to use!
